Detailed Description

An early American geographer often considered to be the father of American topographic mapping, Henry Gannett (1846–1914) began mapping topography as a member of the Hayden Geological Survey of 1871. Many USGS mapmaking methods and standards were later developed under his leadership, and the USGS Geography Program was established under his direction.
